Patches to the rescue | MIT Technology Review
In tests, 26 times more of a drug passed through pig skin than was possible without ultrasonic assistance.
Meanwhile, researchers led by Ana Jaklenec and Institute Professor Robert Langer, ScD ’74, of the Koch Institute for Integrative Cancer Research have developed a small mobile printer that produces patches with hundreds of nearly painless microneedles, whose tips dissolve under the skin to release a vaccine; a study shows they can effectively vaccinate mice against covid-19.
Once printed, the vaccine patches can be stored for months at room temperature. A prototype can produce 100 in 48 hours, but the researchers expect that could be improved.
“We could someday have on-demand vaccine production,” says Jaklenec. “If, for example, there was an Ebola outbreak in a particular region, one could ship a few of these printers there.”
